[mapserver-users] Using dimensions with MapServer as WMS client

[Yewondwossen Assefa]

Alexandre,


  Only wms_time is supported by mapserver acting as a wms server. It is 
also the only dimension that is advertised through the capabilities 
document.  From what I can I see the map context only loads/save the 
dimension into Mapserver metadata, but it is not used for anything.

  Best Regards,
